3 Claims. (Cl. 30-229) This invention relates to cutlery and moreparticularly to an implement which is operated in a manner similar to apair of shears or scissors and is used for forming notches in marginalportions of dress goods cut by means of a pattern pinned dat upon thedress goods.

Patterns used for cutting dress goods are marked along their edges withV-shape'd marks or notches and after the goods is cut notches are formedat these points which are V-shaped and Serve as guides so that edges ofthe goods may be folded to form seams, the notches also serving asguides in order that companion cut pieces or elements of a dress orother garment may be accurately assembled. Care must be taken whencutting the dress goods to form the notches as the notches may be of apredetermined depth in order to form a seam of the proper width and acorrect seam formed when sewing companion portions of the garmenttogether. Often the notches are not properly cut, thus spoiling thedress goods and considerable time and care is required in order toaccurately cut the notches.

Therefore one object of the invention is to provide an implement by useof which notches may be quickly and accurately formed and withoutspecial skill by the person using the notching implement.

Another object of the invention is to provide an implement which is usedin the same manner f as e. pair of scissors or shears and will thus bevery easy to operate.

Another object of the invention is to provide a notching implementhaving male and female jaws or blades, the female blade being formedwith an opening through which the male blade passes and is pivotallymounted so that they may have tilting movement imparted to them byhandles corresponding to scissors handles and the blades caused to cutV-shaped notches in marginal portions of a pattern.

Another object of the invention is to provide the implement with bladesso constructed that the male blade may be shifted longitudinally in theopening of the female blade as it 'moves towards a cutting position andthus allow the tapered end of the male blade to be moved into positionto t snugly in the tapered front end portion of the slot or opening andaccurately form a V-shaped notch in the marginal positions of a patterncut from dress goods.

Another object of the invention is to provide a spring which urges themale blade forwardly and is of such construction that it may be firmly`mounted upon the rear portion of the female 2 blade back of the slot oropening through which the male blade passes.

Another object of the invention is to provide notching scissors whichare of simple construction, easy to operate and which may bemanufactured at low cost.

The invention is illustrated in the accompanying drawings wherein:

Fig. 1 is a view showing the improved notching scissors principally inside elevation and partially in longitudinal section with the male bladein its normally raised position.

This improved notching scissors has two companion blades I and 2 whichare formed of steel and may be referred to as a male blade I and afemale blade 2. The female blade is elongated longitudinally of thescissors and has a rearwardly extending shank 3 provided at its rear endwith a handle 4. The blade 2 is flat throughout its length, as is alsoits shank 3 and in this blade is formed a slot or longitudinallyextending opening 4 having its forward portion 5 tapered to a point atits front end providing the slot with a V-shaped terminal portion havingsharpened side edges 6. Upstanding flanges 'I extend along oppositesides of the rear portion of the opening l and are formed near theirfront ends with oppositely disposed longitudinally extending slots 8.Between rear ends of the side flanges extends a rear flange of cross bar9 having a forwardly projecting lip I0 defining a seat I I which is openat its front and closed at its opposite sides by the side flanges. Thefemale blade and its shank and handle are therefore formed as a singleunit. The male blade I has a shank I2 which is pro- 3 vided at its rearend with a handle i3 disposed under the handle i of the female blade.

The male blade extends forwardly at an upward incline from its shank andat its front end this blade is formed with a tapered or triangular headIii, the portion l5 of the blade rearwardly of the head being bent toextend forwardly at a downward incline so that the head will be disposedparallel to the blade 2 and fit snugly in the tapered forward endportion 5 of the opening when the male blade is swung downwardly to theposition shown in Figure 3. This head is sharpened along its side edgefaces lfand rear portions of these side edge faces are bevelled to formcam surfaces il which engage the converging edges of the tapered end 5of the opening and serve as guides for directing the head into thetapered front end portion of the opening in the female blade and imparta sliding movement to the male blade when the male blade is swungdownwardly to a cutting position. An opening or slot i8 is formedintermediate the length of the diagonally extending portion of the maleblade and at opposite sides of this opening are provided ears IScarrying a pivot pin Zi) which has its end portions projecting fromopposite sides of the male blade and engaged through the slots 8. Themale blade will thus be pivotally connected with the female blade andmay be shifted longitudinally of the female blade in order to cause thehead I4 to fit properly in the tapered front end 5 of the opening l whenmale blade is swung downwardly during a cutting motion. The male blademust be urged forwardly and in order to do so there has been provided aspring il! which is formed from a strip of resilient metal. This springextends longitudinally of the two blades and over the male blade withits downwardly offset rear end portion 22 disposed in the seat l i forabutting engagement with the lip lf3. The front end portion of thespring is bent to form a hook 23 having a bill 2li, and when the hook isdisposed between the ears le with itsbill about the rear surface of thepin 2i; this spring will exert forward pressure upon the pin and urgethe male blade forwardly until its ends are at front ends of the slotsWhen this implement is in use it is grasped by its handles, a thumbbeing passed through the handle l and one or more ngers being passedthrough the handle i3 so that the notch cutter will be held in one handand the blade i may be swung towards the blade 2. The marginal portionof the pattern and the dress goods to be notched will then be engagedbetween the blades, with the blade 2 under the dress goods and the bladel over the pattern, and the notching scissors shifted along the patternuntil the tapered end portion 5 of the opening d is directly under anotch marked upon the margin of the pattern and the head i4 disposedover the notch. Pressure is then applied to the handles and the blade lwill be swung downwardly the blade and during this movement the bevellededges ll of the head ill will guide the head into the tapered end 5 ofthe slot d. At the same time the male blade will be shifted rearwardly ashort distance against action of the spring 2i by the cam surfaces iland as the head i4 moves into the tapered front end of the opening 5shearing action will take place along the sharpened edges of the twoblades and a portion of the marginal edge of the dress goods cut out toform a V-shaped notch exactly corresponding in size and location to thenotch marked upon the pattern. When pressure upon the handles isrelieved the blade l may be returned to its raised position and it willbe yieldably held in the normal position shown in Figure l by action ofthe spring. The notches will therefore be easily and accurately formedin the dress goods.

Having thus described the invention, what is claimed is:
